CamNtech The Actiwave User Manual page 33

I have two or more
EDF files that I wish
to join together –
how do I do this?
The Recordings are
very noisy:
The Actiwave won't
communicate and I
get a message about
'A device which may
be an Actiwave has
been detected':
What are the
potential effects of
Electromagnetic
interference?

screen instructions to update the firmware and do not remove
the device or interrupt the process.
See Appendix 3: Joining EDF files.
The typical causes of noisy data are due to pad selection and
poor skin preparation. See sections 6.1 and 6.2 for advice.
Mains noise may in rare cases cause a problem; see section
9.1.1 for details of filtering this noise.
The battery in the Actiwave is below the level required to
communicate. This message is a safety warning to prevent users
of other CamNtech products attempting to use the wrong
interface. Leave the Actiwave in the dock to charge and check
again later.
The Actiwave system was designed to minimise the effects of
external EMI upon the device and to minimise the effect upon
the environment from the device. The system conforms to the
appropriate standards with respect to EMI performance (see
section 11.7). In cases where strong EMI does affect the
Actiwave, the device will recover with no user intervention.
